A reconfigurable, dual-band, MIMO antenna apparatus, a planar MIMO antenna system utilizing the antenna apparatus, and a method of transmitting and receiving a signal by the antenna apparatus are provided. The apparatus includes a dielectric planar substrate, a first element, a second element, two varactor diodes per element, and a microstrip feed-line. The first element and the second element each have slotted concentric annular rings. The second element is separated on the dielectric planar substrate from the first element, but is coplanar on the dielectric planar substrate with the first element. The two varactor diodes are placed in series with biasing circuitry, the biasing circuitry including RF chokes and current-limiting resistors. The microstrip feed-line feeds both antenna elements. The dual-band antenna elements can each be independently and concurrently tunable to two signal frequencies bands.

A communication device includes two antennas operational within a first frequency range in the communication device. An integrated isolating antenna array component is positioned between the two antennas in the communication device to reduce radiofrequency coupling between the two antennas. The integrated isolating antenna array component includes an interconnection substrate and an antenna array adjacent to the interconnection substrate and including one or more radiating elements. The antenna array is configured to drive the one or more radiating elements within a second frequency range in the communication device. The second frequency range is higher than the first frequency range. The integrated isolating antenna array component also includes an isolator affixed to the interconnection substrate and configured to be connected to electrical ground. The isolator is configured to reduce the radiofrequency coupling between the two antennas within the first frequency range.

A system of antennas, each having disparity operating frequencies, are incorporated into the same aircraft body panels. HF antennas define loops with large internal areas; additional higher frequency antennas are disposed within that large internal area. The higher frequency antennas are sufficiently different so as to prevent coupling. Antennas operating in the same frequency range, disposed on different parallel surfaces are operated in concert as a steerable array.
